Enter the amount from line 28 of your employment tax statement:
"Contributions to private health and nursing insurance or minimum insurance allowance"

This amount is not automatically considered in the calculation of special expenses; it is only used by the tax office to determine whether you are required to submit a tax return.
You must enter the actual contributions to private health and nursing insurance yourself under “Insurance and pension expenses → Health and nursing insurance → Private health and nursing insurance”. You can find these in the contribution statement from your private health insurance.
